Your Voice Can Give Away Your Personality in a Half-Second

They Had You at Hello

People judge you based on a split-second of your voice.

A new study had 64 people record a passage that included the word hello, extracted each individual’s salutation, and played the words back to 320 listeners. Not only did all of the listeners form personality profiles after hellos lasting less than a half-second, 92 percent of them developed the same profile for each voice.
